BLACK+DECKER BC15BD 15 Amp 12V Bench Battery Charger - Reliable

In this review of the BLACK+DECKER BC15BD the bottom line is straightforward: this unit is for vehicle and marine owners who need a dependable, automatic charger and occasional engine start capability. It stands out because the 15 amp bench charger combines routine maintenance with a 40 amp engine start mode and a battery reconditioner, so it not only charges but can revive underperforming 12V AGM, GEL, or WET batteries. The LCD and automatic three-stage charging make it simple to use for DIYers and small workshops alike.

Key Features

• 15 Amp Bench Charging: Provides steady high-frequency charging suitable for maintaining and charging any 12V AGM, GEL, or WET automotive or marine battery.
• 40 Amp Engine Start: Offers a burst mode that can re-start most vehicles in up to 90 seconds without fully replacing a starter or tow service.
• Three-Stage Automatic Charging: Automatically switches from fast charge to top-off to trickle charge to keep batteries at optimal capacity during long storage.
• Battery Reconditioner: Detects sulfation and applies a reconditioning routine to improve a battery's ability to accept and hold charge, potentially extending battery life.
• Alternator Check & LCD: Built-in alternator check indicates whether the alternator is maintaining battery level and the LCD shows charging and battery status with clear icons.
• Safety and Compensation: Reverse polarity protection and AC low-voltage compensation for use with extension cords ensure safer, more reliable operation.

Who It's For

This charger is ideal for owners of motorhomes, boats, jet skis, lawn tractors, ATVs, snowmobiles and cars that sit idle for extended periods and need a reliable maintainer and occasional jump-start assistance. DIY mechanics and small shops will appreciate the bench-style layout, digital display and alternator check for routine battery care and troubleshooting.

It may be less well suited to users who need a lightweight, ultra-portable unit for occasional roadside jumps only, or anyone who requires extremely fast high-current charging beyond a brief 40 amp engine start. For heavy commercial use or large battery banks, a dedicated high-capacity charger would be more appropriate.

Pros & Cons

Pros

• Solid three-stage automatic charging keeps batteries at optimal capacity with minimal user input.
• 40 amp engine start gives a practical emergency restart option without special equipment.
• Battery reconditioner can reverse sulfate build-up and improve charging capability on marginal batteries.
• Clear LCD and alternator check simplify diagnosis and monitoring during charging.

Cons

• The 40 amp start is temporary and not a substitute for a full jump starter in all roadside scenarios.
• Some users report differing opinions on long-term value and charge rate expectations versus simpler chargers.
